On a Friday afternoon in late July, I was on the Mason-Dixon Line as a severe thunderstorm swept across Washington and Franklin counties. As threatening clouds moved into the area, I paused and captured a few photos at one of the markers along the line. Earlier in the winter, I had explored points along the boundary in Western Maryland as part of my work as a guest curator for an exhibit at Frederick Heritage called “Reading Between the Line: The Mason-Dixon Line that Broders North and South.” Just north of Hagerstown, this location is an unincorporated Franklin County community called Mason and Dixon.
